How to say hot in Serbain?

Hello,

First of all, I should warn you that I'm not a native speaker, so take anything I say with a pinch of salt :)

"Hot" in Serbian, when talking about the weather, is "vruć". By the way, I believe "today is cold" should be "danas je zima" or, using "hladan" instead, "hladno je".

Hope this helps,

Alvin
